ABSTRACT:
The method of determining the magnitude of the differential static correction between adjacent records in seismic record processing, that involves the steps of: recording a first multi-trace record responsive to a first seismic wave generated at a first source point; recording a second corresponding multi-trace record responsive to a second seismic wave at a second source point, which is adjacent to the first source point; correlating a first trace of the first record with the corresponding first trace of the second record, and determining the first time difference between the two first traces of said two records; repeating the correlation step and determining the time differences for a plurality of N pairs of traces; adding all of the N time differences and dividing the sum by N to find the net difference in static correction between the first and second source points.
